Which cases of horizontal centrifugal pumps need to shut down for maintenance
Author:
It is inevitable that the horizontal center-open centrifugal pump malfunction, according to different situations, we are dealing with the problem in different ways, and when the equipment in the process of operation, if the following conditions occur, must be stopped to check the treatment.
1, double suction pump pumping empty or cavitation phenomenon occurs, the pump pressure changes abnormally, the pump body is hot.
2, the pump body prick water, the machine pump rotor shift or injection station system occurs prick leakage. Pipeline rupture.
3, water in the shaft tile, serious discoloration of lubricating oil or high water content.
4, high pressure of water injection pipeline, double-suction pump discharge is very small or no discharge of water, very low efficiency.
5、Unusual sound or violent vibration of the unit.
6、Personal accident caused by double-suction pump operation.
7、Sudden and large fluctuation of motor current.
8、Smoke or burnt smell due to the temperature of the machine and pump exceeding the specified value.
In the above cases, we must first stop the machine to check, find the problem and solve it before we can start the machine again. Here to explain a point, many customers for double suction pump is not particularly understand, buy back directly thrown in the sump and start working, without doing a little protection measures, this is not right, the life of the pump will also be fatal damage. So it is recommended that customers should buy back with a control box, so that if problems arise, the control box will play a specific protective role.
